For stronger encryption you will need to encrypt the data itself. You can use the agraham's Encryption library: Basic4android - Encryption However you should consider what to do with the password. If it is stored as a string in your code then a hacker can find it and decrypt your database. I'm not sure about your use case, but if it is possible it is usually recommended to ask the user to supply the password. Upvote 0
